CAR-COUPLING.

Specificaton of Letters Patent.

Application filed November 13, 1913.

Seria1 No. 800,849.

To aZZ- whom -t may coace'm Be it known that I, JOHN O. TAYLOR, aV

citizen of the United States, residing at Findlay, in the county of Hancock and;

State of Ohio, have invented certain newV erence being had therein to the acoompanying drawing.

My invention relates to improvements 1n oar-oouplngs.

The object of my invention is to provide a oar-coupling of the Janney type 1n which the knuckle will -by gravity automatically swing outwardly after the lock for holdlng the same has been released.

Another` object of my invention is to so provide the knuckle that it can be readlly removed and inserted, whereby the asseinbling of the several parts in the manufacture of the ooupling is readily accomplished. p

A further object of my invention is to provide a look which will more securely hold the knuckle in its inward position and at the same time providing a simple construction and operation, and also providing means whereby the parts are readily assembled.

A still further object of my invention is to provide a simple, cheap and effective coupling of this oharaoter haying certain details of structure hereinafter more fully set forth.

In the accompanying drawings: Figure 1 is a top plan view of a coupling embodying my invention showing the draw-head partly broken away to show the knuckle and the locking latch. Fig. 2 is a perspective view of the coupling showing the knuckle removed and showing the draw-head in horizontal section. Fig. 2a is a p'erspective view of the knuckle. Fig. 3 is a Vertical sectional view taken on the line 3-3 of Fig. 1. Fig. 4 is a Vertical sectional view similar to Fig. 3 of the modified form of pivotally mounting the knuckle. Fig. 5 is a perspeotive view of the looking latch.

Referring now to the drawings, 1 represents the draw-head which is of the ordinary J anney type exterior oontour and needs no further description. The draw-head, as shown in Figs. 1 and 2, is of a hollow form and provided at its lower end with an obliquely arranged slot 2, having the obliquely arranged slanting fianges 3, upon which rest the looking latoh 4. This slot 2, as shown, is arranged directly in the center of the draw-head and the latoh 4 is adapted to lock the knuckle in its inward position, as will Abe hereinafter V more fully described. The draw-head at one side is provided at its upper and lower edges with the' outwardly extencling horns 5 and 6, between which the knuckle 7 is pivoted. The cars 5 and 6 are provided with Vertical openings 7 and 8 through which the pin 9 passes. V This pin also passes through an opening 10 in the knuckle and whereby the knuckle is pivotedly mounted between the ears 5 and 6. The horn 6 surrounding theopening8,is provided with an upwardly extending sleeve 11, which has aworm 12 'on its exterior. Said worm eXtends only partially around thereof, as shown in Fig. 2 of the drawings. The knuckle 7 is provided with a oylindrical portion 11, which has itsI lower end provided with a circular reoess l'having one side cut away, as indicated at 13, which allows the knuckle to be readily inserted between the ears 5 and 6, and alsoA allows the sleeve 11 to pass within the ciroular opening 12. The opening 12 is providedwith a worm groove 14 adapted to receive the worm carried .by the sleeve 11, for the purpose, all of which will be hereinafter more fully desoribed'.

The sleeve 114 andiits worm not only serves as a means for oausing the knuckle to swing outwardly, but also serves as an additional bearing for lthe knuckle to work upon, as olearly shown .in Fig. 3 of the drawing. The bolt 9, das heretofore described, passes downwardly through the horns 5 and 6 and through the opening 10 in the oylindrioal portion 11 of the knuckle, and serves as a pivot upon which the knuckle swings. A cotter pin 15 is employed to prevent the up- -ward movement of the bolt 9, although any other well-known looking means could be employed to prevent this upward movement of the bolt.

The portion 16 of the knuckle is that which extends across the draw-'head and forms the ooupling inter-looking with a similar coupling carried by the other car. The portion 17, when the knuckle is in its coupled position, passes inwardly into the hollow draw-head and the looking latoh 4, moves downwardly beyond the same and is engaged by the portion 17, whereby the knuckle is preventcd from swinging outwardly.

The looking latch 4 is of a solid triangular form having at its side the curved portions 17 which rest upon th-e inclined fianges 3 of the draw-head, and whereby it is free to slide thereon. The center of the looking lever ll is provided with a downwardly extending flange 18, which is adapted to fit between the flangcs 3 and whereby it is prevented from twisting in the draw-head and yet have a free movement up and down within the slot 2. The upper edge of the locking latch is provided with an ear 18, through which passes a cable 19, which passes upwardly and outwardly through an opening in the upper end of the draw-head, whereby the looking latch may be drawn upwardly in the slot 2, to bring it in rear of the arms 17 of the knuckle so that the knuckle is free to swing outwardly.

The knuckle, as shown, is of very heavy form and made of metal and when the latch is drawn upwardly so that the arm 17 is not engaged thereby, the same will swing' outwardly along the worm 12, of the sleeve 11 and automatically opened. It being understood that when the knuckle is swung inwardly in its ooupling position, it is raised by the worm engaging groove 111 and the minute the lock a is drawn rearwardly away from the arm 17, the knuekle by gravity swings outwardly.

In Fig. 4, instead of having the bolt 9, extend all the way through the knuckle, the knuckle is simply provided with a recess 21, into which a pin 22 extends, the pin 22 being secured in the ear 5, by means of a transverse pin In this form it will be seen that the pin 22 forms the pivot at the upper end and the sleeve or extension 24 forms the pivot at the lower end. In this form the cylindrical portion 11 of the knuckle is cut away, as indicated at 13, in preoisely the same manner and is provided with the worm connection for causing the knuckle to swing outwardly, as heretofore described.

I'Vhile I have'shown and described this specific form of looking latch and knuckle, it will be seen that this could be varied. without deperting from my invention.

I'Iaving thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A car coupling comprising a hollow draw-head having ears at its upper and lower edges adjacent one side, one of said ears having an upwardly extending lug providcd with a. worm, a knuckle between the said ears and having a recess to receive the upwardly extending member and having a worm groove to receive the worm, whereby the knuckle will swing' outwardly by gravity, and means for looking the knuckle in its inward position, substantially as shown.

2. A car-coupling comprising a hollow draw-head, ears extending from the upper and lower edges adjacent one side, the lower ear having an upwardly extending member provided with a. worm around a portion thereof, a knuckle fitting between the ears and having a recess in its lower edge provided with a cut-away portion to allow the upwardly extending member to enter the same and said recess having a worm groove to receive the worm of the said member, whereby the knuckle is raised when moved inwardly and a sliding looking lat-ch within the draw-head for locking` the knuokle in its inward position.

3. A car coupling comprising a hollow draw-head having horns at its upper and lower edges adj acent one side, the lower horn having an upwardly extending sleeve having a worm on a portion thereof, a knuckle having a cylindrical portion between the horns, the lower end of the cylindrical portion having a Vertical recess having one side cut away to allow the sleeve of the lower horn to pass therein and the said Vertical recess having a worm groove to receive the worm of the slecve, a pin passing downwardly through the harness and the cylindrical portion of the knuckle, and a latch adapted to lock the knuckle in its inwardly raised position.

In testimony whereof I hereunto aflix my signature in the presence of two witnesscs.
